A systems administrator is tasked with enhancing the security of a high-availability server cluster by implementing a third factor of authentication. The current access method requires a smart card and a PIN. To meet the new security policy, the additional factor must be a biometric control. Which of the following should the administrator implement?
The correct answer is a fingerprint scanner. Multifactor authentication (MFA) relies on combining two or more authentication factors: something you know, something you have, and something you are. The existing controls are a smart card (something you have) and a PIN (something you know). A fingerprint scanner is a form of biometric authentication, which falls under the "something you are" category.
A one-time password (OTP) token is a "something you have" factor. A knowledge-based authentication (KBA) question is a "something you know" factor. RADIUS server authentication describes an authentication protocol and server architecture, not an authentication factor itself.
